is that right. just want to know how much it really holds so i dont mess up my mixture

You shouldn't have to worry about that, since the mixture is just percentages. If you need to add, just premix the right concentration and add whatever you need. If you're just adding a little, you can probably add all distilled water. It's not like we ever have to worry about below 0 temps here anyway.
